trysil-json

trysil-json is a cursor rule for Cursor from davidlastrucci/trysil-ai-skills. It costs 2,127 tokens per session, scanned A, original, no licence file.

Rules for converting Trysil entities and datasets to and from JSON, a text format commonly used for exchanging structured data. They apply to Delphi code using the Trysil.JSon module and its serialization helpers.

In plain words
What is it for?
Use them when writing or reviewing Delphi code that serializes entities, lists, datasets, or metadata, or serves Trysil entities as JSON.
Why use it?
They reduce mistakes when exposing Trysil data through JSON or reading JSON back into entities. They also clarify when the rules should be applied during code work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

trysil-json scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
